|dw:1439316532827:dw| these are your coordinates, it's the same thing as finding slope

3. Astrophysics

$rate ~of~change~=\frac{ y_2-y_1 }{ x_2-x_1 }$

4. anonymous

is the answer -2?

5. Astrophysics

Try again, y's in numerator, x's in denominator

6. anonymous

i keep getting -2

Oh you're right! :)
